How do I use a text file input with GDB online in C++?

asked Nov 23, 2023 by John Tupps (130 points)

I have a program written that I feel is correct. It is my first time using a .txt file for input. I run the program with no errors but the answers are all 0.00 for the calculations. I feel that the compiler is not accessing the .txt file input. Is that because it is an online compiler? How does it link with the computer that is running the program?

Files on your computer cannot be accessed from OnlineGDB. You can add the file to your project via the UPLOAD FILE button left of the green RUN button. Then you can refer to the file with a relative path.

If this doesn't quite help, please, share your code.
